Why do the electrostatic field lines not form close loop

Posted by Tahir Md Salman 8 years ago

CBSE > Class 12 > Physics

7 answers

Naina Vashishth 8 years ago

See first of all electrostatic field lines are conservative in nature so being conservative in nature the ensure that the network done must be zero and if electrostatic field lines were to form loops then they would surely give a work done which is non zero so electrostatic field lines and formation of loops are two contradictory things.

Naina Vashishth 8 years ago

Also there is no principle for potentiometer wire. You can use any suitable wire.

1Thank You

Abhay Bhardwaj 8 years ago

According to principle of potentiometer,potential difference across any length of wire is directly proportional to the length of that portion of wire.

1Thank You

Naina Vashishth 8 years ago

The fall of potential across a given length of the wire is directly proportional to the length of the wire provided the wire is of uniform area of cross section and a constant current is flowing through it.
